NEED HELP ASAP What is K if y varies directly with x, and y = 27 when x = 9 k = 3 k = 243 k = .33 k does not exist

lol

step-by-step explanation:

ian gonna lie that is way to much

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
